STOCK` ELEVATOR AND LOADER.

Application lediulyi'l, 1926.` Serial NQ, 120,943.

provide a hoisting` mechanism for raisingk and lowering loads generally and which isequally well adapted for use in conjunction with a stock yard, warehouse, store, garage, or other place where sundry articles,. merchandise and? the like is required to be elevated, or lowered and the same may be installedas a permanent fixture.

lVhile the drawings illustrate a preferred embodiment of the invention it is to be understood that in adapting themeans to meet specific needs and requirements the design may be varied, and such other changes in the minor details of construction may be resorted to within .the scope of the invention as claimed, without departing from the spirit thereof. g

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawings hereto attached in which,-

Figure 1 is a side view of a hoistingmechanism embodying the invention, parts being broken away,

`Figure 2`is a horizontal sectional view on the line 2-2 of Figure 1,

Figure 3, is a transverse sectional View 011. the line 3 3 ofFigure 1, looking in the di# rection of the arrows,

Figure 4 is a fragmentary sectional view on the line 4-4 of Figure 1, looking in the direction of the arrows,showing the parts on a larger scale, and

Figure 5 is a `detail sectional view on the line 5,5 of Figure 1.

Corresponding and like parts are referred to in the following description and designated in the several views ofthe drawings by like reference characters.

The apparatus comprises a suitable frame work, a load carrier, and an elevating and lowering mechanism. The supporting framework includes corner posts 1, longitudinal sills 2, end sills 3, upper side rails 4, and intermediate uprivhts 5 connecting the upper side rail 4 and longitudinal sill 2 at one side. Suitable braces 6 connect the corner posts 1 with the rails 4 and sills 2. Upper end rails =r 7 connect the corner posts 1 to linsure the formation o f au substantial structure. The

tion ofvloadinlg and unloading.

load carrier comprises a platform 8 which is *strengthened and reinforced from below,l by

bolsters 9 andl this load carrier may be,V of any construction depending upon the parti-` cular application of the mechanism and the special use for which the same is designed.,

A 10 extends vertically from, the ends andl sides of the platform y8 and may prof ]ect to any determinatey height therefrom.

The rim., 10 constitutes. a guard. lThe Vside Vportionsvof the rim, or guard l() are'fiXed,

whereasthe end portions are removable'for` ready access toy and egress from the platform, Y

Side panels 11 and end-panels 11 enclose the platform to prevent stock leaping therefrom y Vwhen the apparatus is in service, and elevating cattle'from a pen into posit-ion for loading upon a" wagon, or other carrier'. These panels are preferably detachable and the end panels 11l are connected to the en d guards 10 whichare removable therewith to facilitate the entrance of stock upon the plat-A form and their exit therefromin the opera- The enclosing panels may be of any preferred construc-` tion and, as shown, consisty of spaced horizontal strips and pairs of vertical strips, or battens 12 between which the horizontal stripsare secured,the.lower' ends of the vertical strips, or battens 12 embracing opposite sides of the guard 10. As shown most clear-k ly inFigure 3, the lower ends of the pairs of vertical strips,y or battens 12 loosely engage opposite sides of the guard 10 along the side of the platform 8, whereas'the lower ends ofthe strips, or battens 12 applied to the endpanels 11a are permanently secured to thev guard. 10 at the ends of the platform 8, so that the end panels and guards are detachable,.as a unit, or gate. Angle brackets 13' are secured tothe ends of the vside panels 11' and ai'e disposed to embrace opposite sides of the panels 11 and 11a at the corners, as shown most clearly in Figure 2.

The load carrier is mounted to move vertically on the corner posts 1 and is directed in its vertical movements by guide rollers 14 which are disposed to engage the inner adjacent sides of the corner posts, as shown most clearly in Figure 4, and in this manner lateral and longitudinal displacement of the load carrier is prevented. The guide rollers 14 are mounted in suitable brackets 15 attached in any preferred and substantial way to the corner portions of the platform or bed vof the load carrier. .As means for raising and lowering the load carrier, screws 16 are provided and extend between the upper side rails 4e and the longitudinal sills 2. Two elevating screws 16 are located at each side of the apparatus and are connected for Each of the elesimultaneous movement. vating screws 16 is mounted at its ends in the rails t and sills .2 substantially, as shown in Figure 5, in which is shown a flanged socket 17 and a journal 18, the latter consisting of a reduced end ofthe screw 16. A

washer 19 is mounted upon the base portionl "is in mesh with apvcompanion bevel gear fastpto the outer end o f ailongitudinal shaft 23. There fare two longitudinal shafts 2) at each side of the apparatus and they are dis. posed 1n longitudinal ahnement and are geared at their inner ends to a transverse vshaft 24 which is located below the platform S and extends beyond the sides there of, as shown most clearly in Figure 2, the projecting ends being provided with bevel gears 25 which are in mesh with companion bevel gears 26 secured to the inner ends of the alined longitudinal shafts .23. The

Vtransverse shafts 24 may be operated from a suitable source of power toe'lfect an elevating, or a lowering of the load carrier. As shown, a sprocket wheel 27 is connected by a drive chain 2S to a sprocket wheel 29 fast to an end of the transverse shaftQet. The sprocket whee 27 is fast to a shaft which is mounted ina cross piece, 30 connecting the uprights 5 and which shaft, for convenience, is provided withka crank 31, whereby the mechanism may be operated by hand.

A nut- 32 is mounted upon each of the elevating screws 16 and coperatestherewith to effect a vertical movement'vof the load carrier, to which the nuts 32 are connected. An L-braelret 3?) is provided for each of the nuts 32 and is pivotedY thereto, as indicated at 34. The brackets 38 are disposed so that their horizontal members engage under the ends of certain holsters 9 to which they are made fast, whereas the vertical members extend along the outer sides of the side guards 1() to Whichthey are connected in any preferred way; By having the nuts 32 pivotally con nected to the load carrier the lattermay receive a limited vibratory movement without imposing undue strain upon the elevat- -in g screws.

l Then the apparatus is adapted for load- -ing stock, it is arranged with one end opposite the chute, or opening of the pen or enclosure to admit of the cattle passing rfrom the pen to the platform 8. .The wagon, or other carrier is located at the oppositefend of the apparatus v to receive the cattle therefrom. After the platform 8 has received the desired load, the entrance thereto from the pen may be closed by vreplacing the end panel or gate previously removed and the platform is elevated by operating the crank 31 which, through the instrumentalities herein set forth, effect a lifting of theplat` form to the requiredjelevation and the cattle are loaded into the wagon, or other carrier by removing the end panel or gate 11a at the outer end of the apparatus. In order that the cross piece' 7 at the delivery end may not interfere with the passage of the stock from the platform to the wagon, thecorner posts 1 at theV delivery end project to a greater height than the corner posts 1.at the receiving end of the apparatus. 1t is evi'- dent from the foregoing `and the drawings hereto attached, that the Vapliiaratus is readily adapted as anelevatorfor usev in stores, warehouses, Vgarages and other places where loads, articles and commodities are required to be raised, or lowered.y

lHaving thus described the invention, I claim: v

In a hoisting mechanism of the character specified, comprising a Aframe-work, a load carrier, mounted within the framewOrlLfOr vertical movement and comprising a bottom, a guard surrounding the bottom, bolstersdisposed beneath the said bottom, angle brackets attached to the bolsters and guard, elevating screws mounted upon the frameworlr and nuts mounted uponthe elevating screws and pivoted to the said angle brackets.` l Y In testimony whereof Ialfix my signature. l
